Abstract
The utility model relates to a desirable sacrum fixing plate. The sacrum fixing plate has a desirable shape, and comprises head parts at the two ends and a connecting part in the middle; and fixing holes are formed on the head parts at the two ends and the connecting part in the middle. Compared with the prior art, the desirable sacrum fixing plate has the advantages of safety, effectiveness, convenience in operation, and the like.
Description
Technical field
This utility model belongs to technical field of medical instruments, especially relates to a kind of type rumpbone fixing head as one wishes.
Background technology
Fracture of pelvis is more common in vehicle accident, high-altitude high-energy damage such as fall, and all unstable on vertical and horizontal direction, sacroiliac joint separates, longitudinal fracture of the sacrum is one of the most serious type of damage in the fracture of pelvis, and it treats difficult, and complication is more.Chinese scholars is advocated positive open reduction internal fixation treatment at present, to reduce its disability rate.Various in recent years operation fixing meanss day by day increase, as sacrum rod fix, the sacro-iliac joints screw is fixed, reconstruction plate, screw combine GaLveston technology internal fixation etc.Sacrum rod has the ability of good anti-vertical shear, but the ability reversed of nonreactive almost; When adopting the sacro-iliac joints screw fixedly, it is prone to cause caving in of nail tail loosening in the single-point contact of ilium face; Reconstruction plate has certain anti-vertical shear and anti-torsion ability, but its fixed range is limited; It is that single rod inserts the bone wing that screw combines GaLveston technology internal fixation, has the fine motion between rod and ilium.More than the biomechanical property of these factors influence internal fixation, and variously have that specification requirement is high, operation wound is big, shortcoming such as strong insufficient rigidity, nerve and blood vessel injury complication are more.
The existing sacrum nail that adopts carries out technique for fixing, and the sacrum nail runs through sacroiliac joint, belongs to bidimensional and fixes, and intensity is low; The danger of damage sacral nerves is arranged, need C type arm x ray machine, specification requirement is higher, adopts the sacrum rod technology; Fixedly the bilateral ilium reaches the indirect securement purpose, and intensity is less, and difficulty resets.
Summary of the invention
The purpose of this utility model is exactly for the defective that overcomes above-mentioned prior art existence a kind of safe and effective, easy to operate type rumpbone fixing head as one wishes to be provided.
The purpose of this utility model can realize through following technical scheme: a kind of type rumpbone fixing head as one wishes; It is characterized in that; This fixing head is moulding as one wishes, comprises the head and the intermediary connecting portion at two ends, and the head at two ends and intermediary connecting portion are equipped with fixing hole.
The dissection profile of the shape of described fixing head and sacroiliac joint and rumpbone dorsal part is complementary.
The head at described fixing head two ends is provided with circular fixing hole, and intermediary connecting portion is provided with oval fixing hole.
Be arch in the middle of the described connecting portion, its arch shaped length is according to the model difference of steel plate and length is different, and length is between 2.5-3.5mm.Both sides are arranged with two pairs of oval fixing holes, and wherein the major axis of a pair of oval fixing hole is 15mm, and minor axis is 6mm, and another major axis to oval fixing hole is 10mm, and minor axis is 4mm.
The head at described fixing head two ends is equipped with two circular fixing holes side by side, and the diameter of circular fixing hole is 6mm, and the spacing between two circular fixing holes side by side is 4mm.
Described fixing head is bent titanium alloy sheet.
Compared with prior art, this utility model fixing head has the following advantages:
1. can be used as the rumpbone fixing head, can be simultaneously fixedly ilium, lateral masses of sacrum (ala sacralis), rumpbone pedicle of vertebral arch;
Fixedly sacroiliac joint separate, rumpbone longitudinal fracture dedicated fixed plate, fixing head fully takes into account the dissection profile of sacroiliac joint and rumpbone dorsal part, can effectively keep to reset; The all available multiple spot in two ends is fixed, and reaches three-dimensional fixation, and is strong reliable;
3. elliptic design is adopted in lateral masses of sacrum, pedicle nail hole, is convenient to adjust the screw position and accurately implants; Ilium and lateral mass screw adopt diameter 6mm cancellous bone screw, and be strong, and the rumpbone pedicle nail adopts the 4.0mm cancellous bone screw fixing safe and effective;
4. steel plate adopts the titanium alloy manufacturing, and intensity, histocompatibility are reliable, and can bending moulding, the middle part different length be provided with the series length steel plate, to satisfy the difference between the individuality;
5. direct-view is performed the operation down and three-dimensional fixation, has avoided beating through ilium sacrad vertebral body the danger of hollow nail damage sacral nerves, and the sacrum rod that connects bilateral ilium rear side is fixing reliable;
6. this utility model fixing head can be protected the post-decompression nerve of sacrum bone vertebral lamina simultaneously.
Description of drawings
Fig. 1 is the structural representation of this utility model;
Fig. 2 is the side view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment this utility model is elaborated.
Embodiment 1
Shown in Fig. 1-2, a kind of type rumpbone fixing head as one wishes, this fixing head is moulding as one wishes, is complementary with the dissection profile of sacroiliac joint and rumpbone dorsal part.Comprise the head 1 and intermediary connecting portion 2 at two ends, the head at two ends and intermediary connecting portion are equipped with fixing hole.
Be arch 6 in the middle of the described connecting portion, its arch shaped length is according to the model difference of steel plate and length is different, and length is between 2.5-3.5mm.Both sides are arranged with two pairs of oval fixing holes, and the major axis of wherein a pair of oval fixing hole 3 is 15mm, and minor axis is 6mm, and another major axis to oval fixing hole 4 is 10mm, and minor axis is 4mm.
The head at described fixing head two ends is equipped with two circular fixing holes 5 side by side, and the diameter of circular fixing hole is 6mm, and the spacing between two circular fixing holes side by side is 4mm.
Described fixing head is bent titanium alloy sheet; Intensity, histocompatibility are reliable, can shear arbitrarily, bending is moulding, and the middle part different length is provided with the series length steel plate; To satisfy the difference between the individuality; Can shear length and position (as can central authorities cutting off monolateral use, also can bilaterally fix simultaneously and use) that is fit to according to actual needs according to the build and the damaged position of sufferer, the ready-formed arc of fixing head can be good at adapting to rumpbone and sacroiliac joint form; The sacral nerves that can well protect canalis sacralis decompression back to expose, length is processed different model to adapt to different rumpbone types through increasing middle part length.Two pairs of oval fixed hole position set, are convenient to adjust the screw position lateral masses of sacrum, pedicle nail are accurately implanted during use in lateral masses of sacrum, pedicle of vertebral arch place; Ilium and lateral mass screw adopt diameter 6mm cancellous bone screw, and be strong, and the rumpbone pedicle nail adopts the 4.0mm cancellous bone screw fixing safe and effective.
Above-mentioned type rumpbone fixing head as one wishes can be used for treating that reconstruction behind sacroiliac joint dislocation, the fracture of pelvis that involves sacroiliac joint, rumpbone longitudinal fracture, the Sacral Tumors resection operation is fixed or other aspects are carried out rumpbone and fixed.
Embodiment 2
